vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in building-blocks.

The object of the invention is to provide a building-block the ends of which are so constructed that when engaged with the end of the next adjacent block in forming a wall the meeting ends of the blocks at the inner and outer sides of the wall will be out of alinement, thus forming a break-joint construction which will prevent the passage of moisture or dampness through the joint between the blocks.

A further object is to provide a buildingblock having air-spaces formed through and between the adjacent or meeting ends of the same.

With these and-other objects in view the invention consists of certain novel features of construction,.combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a wall constructed of the improved building-block. Fig. 2 is a detail perspective viewof one of the intermediate blocks forming the body of the wall. Fig. 3 is a similar view of one of the return or corner blocks. Fig. 4 is a similar view of one of the end blocks of the wall. Fig. 5 is a view similar to Fig. 4, showing a shorter block for finishing the ends of a wall; and Fig. 6 is a similar view showing a double form of the block shown in Fig. 1.

Referring more particularly to the drawmgs, 1 denotes the intermediate buildingblocks which form the body of the wall, a detached view of one of the same being shown in Fig. 2 of the drawings. The intermediate blocks are cut away it each end and on opposite sides of the block, as shown, to form re:

cesses 3 and tongues 4, whereby when said 7 blocks are arranged to form a wall the tongues 4 on the end of one block will engage the recess 3 of the next adjacent block, thereby forming an overlapping or rabbeted joint.

The obliquely-disposed meeting walls of the block are cut away, as at 5, to form an obliquely-disposed passage or air-space 6 between the blocks. Between the ends of the tongues 4 and the adjacent walls of the recesses 3 is placed cement orother plastic material with which the blocks are secured or laid up in the wall. The blocks 1 are provided with a vertical obliquely-disposed oblong air-passage 7.

In Fig. 3 of the drawings is shown a return or corner block 8, said block being formed with right-angularly-projecting tongues 4..

The tongue projecting 1n one direction is formed on the outer side of the block, while the tongue projecting in the other direction is formed on the inner side of the block, the recesses or cut-away portions of the block being arranged accordingly. The corner-blocks are provided with right-anguarly-formed vertically-disposed air-passages 9.

In Figs. 4 and 5 are shown two forms of blocks 10 and 11 to be used in building the ends of the walls. The blocks shown in these figures have the tongues 4 and recesses 3 formed on one end only, the opposite ends being square. These blocks are also provided wlth vertical obliquely-disposed airassages 12. The block lO'is longer than the Elock 1 1 and is provided near its squared end with a second vertically-disposed air-passage 13, which is preferably right angular in shape.

In Fig. 6 is shown a double construction of theblock shown in Fig. 1 and is of a form that would be produced by arranging two of the blocks 1 side by side with the tongues of the one engaging the tongue of the other on one end, thus forming a V-shaped tongue 14, and the cut-away portions on the other ends of the blocks coming together to form a substantially V-shaped recess 15 to receive the V-shaped tongue 14 on the ends of the next adjacent block, thus forming a break-joint. This form of block is used for the construction of thick heavy walls.

A wall formed of blocks constructed as herein shown and described will be moistureproof, due to the break-joint or overlapping arrangement of the blocks, while the air-passages formed therein will afiord a free circulation of air through the walls.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without re quiring a more extended explanation.

Various changes in the form, proportion,-

" and the minor details of construction may be break jointfsaid obliquely-disposed walls having formed therein recesses which when the blocks are brought together form vertieally-disposed air-passages and similarly-disposed air-passages formed in the body of the blocks, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
